Dunestar filters ?

Does anyone have experience with the Dunestar bandswitching filter ?
What is the attenuation on each of the non-selected bands ? How much does
the bandswitching impair isolation, compared to the single-band filters ?
Can the "new and improved" Dunestar filters really handle a 150 watt output
transceiver without smoking ?
Send your responses directly to me, and I'll post a summary to the reflector.
